This is pretty ugly. Returning a refernce to a private field? Ouch,
this totally breaks encapsulation

Huh?

In the second approach to implementing singletons, the public member
is a static factory method:

// Singleton with static factory
public class Elvis {
private static final Elvis INSTANCE = new Elvis();
private Elvis() { ... }
public static Elvis getInstance() { return INSTANCE; }
public void leaveTheBuilding() { ... }
}

ITEM 3: ENFORCE THE SINGLETON PROPERTY WITH A PRIVATE CONSTRUCTOR OR AN
ENUM TYPE


provided instance is final, it should be capitalized, else looks pretty
standard to me. ?
